WALL STRUCTURE AND BUILDING BLOCK THEREFOR Filed March 9, 1962 ATTORNEYUnited States Patent 3,222,840 WALL STRUCTURE AND BUILDING BLOCKTHEREFOR Morton M. Rosenfeld, Mount Vernon, N.Y. (271 Madison Ave., NewYork, N.Y.) Filed Mar. 9, 1962, Ser. No. 178,714 4 Claims. (Cl. 52-561)The present invention is a continuation-in-part of my copendingapplication Ser. No. 166,813, filed on Jan. 17, 1962, and entitled Walland Block Therefor.

This invention relates to a wall structure and a building blocktherefor. More particularly, the present invention is directed to a wallformed from a plurality of superimposed courses of blocks with a layerof mortar therebetween and a novel block from which the wall may beconstructed.

The wall and block therefor as set forth in my copending applicationadequately performs its intended function, However, the wall disclosedin my above mentioned copending application suffers from a disadvantagein that it does not present a smooth exterior surface on the wall so asto preclude detection of the fact that it is internally reinforced.

The wall structure of the present invention is preferably madefrom adouble thickness of blocks'which are structurally interrelated in amanner so that they may be superimposed over each other in the variouscourses. By providing a wall structure having superimposed overlappingblocks, it will be obvious that a stronger wall is providedg- 'lheprimary purpose of the wall structure of the present invention isprovided an internally reinforced wall by assemblingblocks and withrespect to previously anchored upright reinforcement rods. 1

It is an object of the present invention to provide a novel reinforcedwall structure.

It is another object of the present invention to provide a novel wallstructurally interrelated in a manner so that it may withstand higherpressures.

It is another object of the present invention to provide a novelbuilding block.

It is another object of the present invention to provide a Wall which ismuch stronger than those proposed heretofore, and yet is capable ofbeing rapidly constructed by a novice.

It is still another object of the present invention to provide a novelwall 'which may be rapidly constructed from blocks which are identicalwith blocks thereabove and therebelow and with a particular orientationbetween the courses.

It is still another object of the present invention to provide a wallcomprised of superimposed overlapping courses of blocks with all theblocks in one course being particularly orientated with respect toblocks in the courses thereabove and therebelow.

It is still another object of the present invention to provide a novelwall having a thickness twice that of the building blocks from which itis constructed, and internally reinforced in a novel manner.

Other objects will appear hereinafter.

For the purpose of illustrating the invention there is shown in thedrawings forms which are presently preferred; it being understood,however, that this invention is not limited to the precise arrangementsand instrumentalities shown.

FIGURE 4 is a perspective view of a typical block utilized in theconstruction of the wall illustrated in FIGURE 1.

Referring to the drawing in detail, wherein like numerals indicate likeelements, there is shown in FIGURE 1 a wall designated generally as 10.

The wall 10 will be constructed of a plurality of overlapping courses.For purposes of the present discussion, wall 10 is illustrated as havinga first course 12 and a second course 14 with mortar 16 disposedtherebetween. It will be noted that the wall 10 has a thicknesscorresponding to twice the width of the building blocks from which it isconstructed. As will be made clear hereinafter, the wall 10 isinternally reinforced.

As shown more clearly in FIGURE 2, the first course 12 may include anend block 18. The end block 18 may be rectangular with side edges of thesame length and end edges of the same length. The wall 10 is preferablyprovided with a width which is twice the width of the blocks 20-27. Theblocks 20, 22, 24, and 26 are in a row. Blocks 21, 23, 25 and 27 are ina second row juxtaposed to the first row. It will be noted that thelength of the block 18 is twice the width of the blocks 20-27 andthereby corresponds with the width of the wall 10.

Each of the blocks 20-27 are identical. Each of the blocks 20-27 isprovided with a notch 28 at one end thereof. The width and length of thenotch 28 is su stantially equal to one-half the width of the blocks20-27 As shown more clearly in FIGURE 4, each of the blocks will have anend face 32 corresponding to one-half the width of the block and an endface 34 which corresponds to the full width of the block. Beforeconstructing the first course 12, a plurality of upright rods 30 will beanchored to the supporting surface in a staggered pattern as illustratedmore clearly in FIGURE 2. When the blocks 20-27 are positioned, it willbe noted that the blocks in the first row are positioned so that theirnotch 28 is internal of the wall 10. Likewise, the blocks in the secondrow are positioned so that their notch 28 is internal of the wall 10.

When the blocks 20-27 are positioned, they have a particularrelationship with respect to the staggered pattern of rods 30. Hence, itwill be noted that a rod 30 is disposed within each of the notches 28adjacent the smaller end face of each of the blocks 20-27.

When the first course 12 has been positioned as illustrated in FIGURE 2,a layer of mortar 16 will be pro vided across the top surface thereof.Sufficient mortar will be provided so that the area of the notches 28will be completely filled with mortar. Thereafter, the second course 14will be constructed. The second course 14 includes an end block 36 whichdiffers from the end block 18. The end block 36 is provided with acorner notch 38 thereby causing the end block 36 to be P-shaped. Oneedge of the notch 38 has a length corresponding to the width of theblocks 2027. The other edge of the notch 33 has a length correspondingto one and one-half times the length of the notches 28.

When the block 20 is positioned, its end face 34 will be juxtaposed tothe shorter side edge of the block 36. The position of the block 20'automatically results in the rod 30 disposed within the notch 28' on theblock 20 to be remote from the smaller end face of the block 20.Accordingly, the blocks 20 and 20 will be staggered with respect to eachother. A corresponding relationship will exist between the blocks 21 and21, blocks 22 and 22, etc. Since the blocks of course 12 will beoverlapped by corresponding blocks in the course 14, the wall 10 will bestronger than a wall constructed with blocks which are merelysuperimposed over one another in the adjacent courses. It will be notedthat the notches 28 on the blocks 20' and 23' overlap each other in acentral portion of the Wall 10. Mortar will be provided within thenotches 28' in the second course 14. Except for the end blocks in thevarious courses, the wall is constructed of blocks which are identicalwith each other. Since the notches on the blocks will be internal of thewall 10, it will be not be possible to detect that the wall 10 isinternally reinforced. It will be noted that the disposition of thenotches 28 and 28 enables the blocks -27 and 20'27' to be inserted froma direction perpendicular to the plane containing the rods 30.

Hereinafter, the P-shaped block 36 may be referred to as a P-shapedstarter block. Hereinafter, the rods 30 may be referred to as astaggered row of upright reinforcement rods. Hereinafter, the notches 28or 28 may be referred to as a corner notch juxtaposed to the planebetween each of the rows of blocks in each course.

The present invention may be embodied in other specific forms withoutdeparting from the spirit or essential attributes thereof and,accordingly, reference should be made to the appended claims, ratherthan to the foregoing specification as indicating the scope of theinvention.
